Step 1: Combine two parts cornstarch and one part Aleene's Tacky Glue (or 1 cup cornstarch with 1/2 cup glue) and mix well for 5+ minutes until a dough forms. If it's too sticky, add more cornstarch, or if it's too dry, add more glue. It should become smooth like a clay.

Step 2: Roll a section of dough with your hands and roll flat with a rolling pin until about 1/4 inch thick.

Step 3: Cut out shapes with cookie cutters, emboss with stamps, paint the dough while wet or tint the dough with paint in a plastic bag to create unique ornaments like these:

• Cactus Ornament: Use a cactus cookie cutter to cut the shape out of dough. Paint with green and coat with green glitter.
• Punny Embossed Ornament: Add dough and paint to a plastic bag and mold until dough is marbled. Use small alphabet stamps to press a punny saying into a circle or oval ornament and paint over the words to bolden.
• Flamingo Ornament: Use a flamingo cookie cutter to cut the shape out of dough. Paint with pink, white and black paint.
• Photo Frame Ornament: Cut a large oval out of dough, then cut a smaller oval out of the middle to create a frame. Decorate with any of the above techniques. Then glue a photo to the back of the frame shape with Tacky Glue. 
• Emoji Ornament: Paint a circle ornament to look like your favorite emoji.

Step 4: Use the straw to cut a hole in the top of the ornament where it will hang.

Step 5: Set dough aside to dry out completely for at least 24 hours.

Step 6: Once dough has hardened, thread string through the holes in the ornaments and tie.
